the registration prefix is "99", then the
recording will be registered with the
gatekeeper with a gatekeeper ID of
"992222"
• register as a service prefix: the numbers
are used as a service prefix for the IP VCR
on the gatekeeper. That means that any
number beginning with the prefix will be
directed to the IP VCR. Any numbers
following the prefix will be identified by
the IP VCR as a recording number (or
folder ID). For example, if a recording has
Numeric ID "3333" and the IP VCR has a
service prefix of "99" registered with the
gatekeeper, then a user dialing "993333"
will be directed to that recording
This setting does not affect point-to-point calls for
which prefixes can be set on a per-folder basis (see
Adding and updating folders).
• a recording console ID, that will start up
the recording console
• a recording ID that will cause the IP VCR
to start a recording and place it in the
folder associated with that recording ID
Using registration prefixes:
• To usefully partition the dialing space, you
might need to ensure that all recordings
registered with a gatekeeper from a single
IP VCR start with the same sequence of
digits
Using registration prefixes also can benefit
large-scale dial plan changes. For example,
you can change all IP VCR registrations to
begin with "121" instead of "11" by
changing a single IP VCR configuration
field rather than individually amending
every recording's associated gatekeeper ID
If you want to use folder IDs in
conjunction with a registration prefix,
check the Register folder IDs checkbox
further down the page
Using service prefixes:
• By using a service prefix, the gatekeeper
will automatically forward calls starting
with the service prefix to the IP VCR. The
IP VCR will determine whether the call
matches a valid recording (in which case
the recording will be played back), folder
ID (in which case the call will be recorded
into that folder) or an auto attendant ID
(in which case the auto attendant is
displayed). If no match is found, the
default incoming call action will be
applied (see Configuring global
connection settings). You do not have to
individually register recordings or folder
IDs with the gatekeeper
These settings will have no effect if H.323 gatekeeper
usage is disabled.
Play back
prefix
Specifies an optional extra prefix that the IP VCR
should register with the H.323 gatekeeper
specifically for play back.
